Description

Auxiliary support device and method of using the same

Technical Field

The present invention relates to the technical field of supporting devices, and in particular to an auxiliary supporting device and a use method thereof.

Background technique

At present, the society has entered an aging society. The elderly and disabled people who are semi-paralyzed or fully paralyzed and cannot take care of themselves due to weakness in their lower limbs and cannot stand or walk, as well as patients with behavioral and living inconveniences caused by postoperative pathological reasons, often need to use auxiliary support devices such as wheelchairs and crutches. There are many auxiliary support devices with different functions in the prior art, but they are still complicated to operate and costly, and are even inferior to simple wheelchairs.

Chinese patent CN110327166A discloses a mobile transposer, which is designed to solve the technical problems of inconvenient production and assembly, high production cost, poor stability and safety, and inconvenient operation of existing similar products. In the mobile mechanism of the mobile transposer, a universal wheel is provided at the bottom of the base, the universal wheel is provided with a brake, and a lifting mechanism is provided at the center of gravity of the top of the base; the key points are that the foot pedal of the lifting mechanism is hinged and fixed to one end of the column, and is provided with a ratchet and a ratchet claw, the foot pedal is located above the base, the foot pedal, the transmission rod and the connecting rod close to the side of the column are hinged and fixed in sequence to form a linkage structure, the top of the connecting rod is fixedly connected to the chest support rod and the handle, the connecting rod is in an "E" shape, and the column hinged fixed end of the connecting rod is extended with a buffer mechanism; a T-shaped handle is provided on one side of the transmission rod of the chest support rod and the handle, the armpit support frame is tilted upward in a V shape and symmetrically arranged on both sides of the chest baffle, and the handbrake on the side of the handle is connected to the ratchet claw through a brake line.

The defect of this patent is that although its lifting mechanism can use the principle of lever to step on the foot pedal with the help of the underarm support mechanism to lift the patient, since the underarm support structure is an upwardly tilted V-shaped underarm support frame, when the patient is lifted, due to the patient's own gravity, the patient's chest will inevitably slide to the bottom of the upwardly tilted V-shaped underarm support frame, and then be strongly squeezed by the upwardly tilted V-shaped underarm support frame, which may even cause serious squeezing injuries to the patient's chest and other soft tissues, and the upper body will inevitably lean forward significantly, and the patient's hands must also hold the handle to maintain body balance, which greatly expands the area occupied by the device when transferring the patient. Due to the complex structure of the lifting mechanism, the operation is very cumbersome, and the nursing staff needs to expend a lot of physical strength to step on the foot pedal, which cannot significantly reduce the labor intensity of the nursing staff. In addition, the device can only be used when the person being transferred faces the side where the handle is located.

Chinese patent CN203328955U discloses a multifunctional sit-up assist machine, including a positioning knob, an adjustment support arm, an underarm support arm, an adjustable flat plate, a vertical support rod, a horizontal support and a universal ground wheel. Universal ground wheels are provided at the lower ends of the horizontal support slightly inward, and a vertical support rod is connected to one end of the horizontal support. The upper end of the vertical support rod is connected to the adjustable support arm through a positioning knob, and the outer end of the adjustable support arm is connected to the underarm support arm. An adjustable flat plate is connected between the two vertical support rods. The vertical support rod and the horizontal support together form an L-shaped structural frame, which serves as the main support device. The device can assist people with inconvenient legs and feet to complete the sitting and getting up movements; assist in walking movements, realize the function of a crutch; and realize the function of a wheelchair.

The defect of this patent is that when the patient needs to get up from the bed or other non-standing equipment, the medical staff must manually carry or lift the patient to the wheelchair, which puts a greater burden on the medical staff's physical strength and is unsafe, making it easy for the patient to fall. In addition, there is a possibility of secondary injury to the patient's lower limbs during the carrying process, resulting in strains or abrasions.

In addition, on the one hand, there are differences in understanding among those skilled in the art; on the other hand, the inventor studied a large number of documents and patents when making the present invention, but due to space limitations, not all details and contents are listed in detail. However, this does not mean that the present invention does not have the characteristics of these prior arts. On the contrary, the present invention already has all the characteristics of the prior art, and the applicant reserves the right to add relevant prior art to the background technology.

Detailed ways

The following is a detailed description with reference to the accompanying drawings.

Example 1

The present application relates to an auxiliary support device, which at least includes a leg rest portion 1. The shape of the leg rest portion 1 can be circular to maintain the maximum use efficiency of the area. The leg rest portion 1 is provided with a plurality of rollers 101 in contact with the ground, so that the leg rest portion 1 can be driven to move or change the parking position according to the rotation direction of the rollers 101. It should be noted that the shape of the leg rest portion 1 can be adaptively selected according to actual conditions, for example, it can be a variety of shapes such as rectangle, triangle, trapezoid, etc. to adapt to different places of use.

The adjusting part 2 has a first end 201 connected to the leg-placement part 1; and the supporting part 3 is arranged at the second end 202 of the adjusting part 2 in the vertical direction. When the adjusting part 2 changes the distance between the first end 201 and the second end 202, the supporting part 3 can change its vertical height accordingly, so that when the patient's legs are placed on the leg-placement part 1, the supporting part 3 supports the patient's upper body, and the height of the supporting part 3 from the ground can be adjusted according to the patient's height to accommodate patients of different body shapes.

According to a preferred embodiment, the support part 3 includes a support plate 303 for lateral support of the patient's upper body area, a first support rod 304 for vertical support of the patient's left armpit, and a second support rod 305 for vertical support of the patient's right armpit. The support plate 303 is configured as a flat plate or an arc shape so that the support plate 303 can fit the patient's upper body to the greatest extent. The first support rod 304 and the second support rod 305 are respectively arranged at both ends of the long side of the horizontal plane of the support plate 303 so that the first support rod 304 and the second support rod 305 can correspond to the position of the patient's armpits. The first support rod 304 and the second support rod 305 extend toward the patient and form a right angle with the support plate 303. After the first support rod 304 and the second support rod 305 extend to the first support point 301, they are changed from a vertical extension state to an oblique upward extension state so that when the patient is supported by the first support rod 304 and the second support rod 305, they will not slide out of the first support rod 304 and the second support rod 305 due to violent movement or other accidents. The support part 3 and the patient's armpits form at least two first support points 301, that is, the first support rod 304 forms a first support point 301 under the patient's armpit, and the second support rod 305 forms another first support point 301 under the patient's armpit, thereby providing strong support for the patient's armpits and assisting the patient to stand.

According to a preferred embodiment, a vertical space for accommodating the adjusting part 2 is provided at a position of the supporting part 3 corresponding to the adjusting part 2. The vertical space may be cylindrical, wherein a accommodating space connected to the inner wall of the vertical space by a rolling bearing and matching the shape of the adjusting part 2 is provided inside the vertical space. That is, the supporting part 3 uses the axis of the vertical space as the rotation axis, and rotates itself around the axis without driving the accommodating space to rotate accordingly. A metal block is fixedly welded to the vertical lower end of the side of the accommodating space close to the patient. The adjusting part 2 may be a "U"-shaped cabin, and the "U"-shaped opening faces the direction of the metal block. The metal block may be rectangular and embedded in the two ends of the "U"-shaped opening of the adjusting part 2, so that the metal block can slide up and down in the adjusting part 2, thereby driving the accommodating space and even the entire supporting part 3 to slide relatively in the adjusting part 2. The "U"-shaped opening of the adjusting part 2 may extend inwardly to the seal, and the two ends of the metal block are located at the seal and are slidably connected at its extended part. The regulating part 2 is divided into two compartments with the metal block as the boundary. The first compartment is a guide rail for the metal block to slide up and down, and the second compartment is separated from the first compartment by a partition. The lower end of the partition vertically reaches the bottom of the regulating part 2, and a certain space is left at the upper end to maintain the connection between the first compartment and the second compartment. A fixed pulley is provided at the upper space of the partition, and the fixed pulley can rotate freely and can stop its rotation by a switch provided at the outer shell of the support part 3. That is, when the switch is turned on, the fixed pulley can rotate freely around its own rotation axis, and when the switch is turned off, the fixed pulley cannot rotate. It can be realized by motor control or other mechanical parts, which is not limited to this. An eccentric wheel is also connected to the fixed pulley, that is, an integrally formed pulley with a different center of circle from the fixed pulley but the same rotation center and rotation speed as the fixed pulley. The diameter of the eccentric wheel is smaller than the diameter of the fixed pulley and the center of circle of the fixed pulley falls on the eccentric wheel. The fixed pulley is provided with a first steel wire connected thereto, and the eccentric wheel is provided with a second steel wire connected thereto, and the first steel wire and the second steel wire do not interfere with each other and both are wound around their own pulleys for several turns to ensure the rotation. One end of the first steel wire is connected to the fixed pulley, and the other end enters from the first compartment and is connected to the metal block. A spring is provided in the second compartment, one end of the spring is connected to the vertical bottom end of the second compartment, and the other end of the spring is connected to the second steel wire. The second steel wire extends from the second compartment and is connected to the eccentric wheel. Thus, a series of continuous transmission components are formed so that the support part 3 can move freely up and down in the adjustment part 2. Its working principle is that: the total weight of the support part 3 is constant (when the patient is not in use), and when the support part 3 is moved downward in the adjustment part 2 by the metal block, the metal block moves downward, and the first steel wire connected thereto moves downward while driving the fixed pulley to rotate, the eccentric wheel rotates accordingly, and the second steel wire pulls the spring, so that the spring tension becomes larger. When the spring tension increases, the eccentric wheel and the fixed pulley do not have the same center, the diameter of the eccentric wheel is smaller than the diameter of the fixed pulley, and the center of the fixed pulley falls on the eccentric wheel, which results in the spring tension force arm being shorter than the force arm of the gravity of the support part 3, and the torque generated by the spring tension force is always equal to the torque generated by the gravity of the support part 3, thereby achieving balance. That is, the patient does not need to use a lot of force to change the height of the support part 3, but only needs to break the balance to adjust the height of the support part 3, and after the height is changed, the patient does not need to hold the support part 3 by hand, and the support part 3 is naturally kept in torque balance without sliding up and down. Then the fixed pulley can be locked by the switch for use.

Similarly, when the support part 3 is moved upward in the adjustment part 2 by the metal block, the metal block moves upward, and the first steel wire connected to it moves upward and drives the fixed pulley to rotate at the same time, the eccentric wheel rotates accordingly and the second steel wire relaxes the spring, so that the spring tension becomes smaller. After the spring tension becomes smaller, because the center of the eccentric wheel and the fixed pulley are not the same center, the diameter of the eccentric wheel is smaller than the diameter of the fixed pulley and the center of the fixed pulley falls on the eccentric wheel, the force arm of the spring tension is longer than the force arm of the gravity of the support part 3, and the torque generated is always equal to the torque generated by the gravity of the support part 3, thereby achieving balance. It should be noted that the above components are performed on the adjustment rod 205 of the adjustment part 2, and the support part 3 moves downward until the bottom of the adjustment rod 205, and then downward to the base 206 of the adjustment part 2.

According to a preferred embodiment, the first support rod 304 and the second support rod 305 can move freely along the long end of the horizontal plane of the support portion 3. Specifically, with the vertical space as the dividing line, sliding grooves 306 are provided at both ends. A sliding rod 307 is provided in the sliding groove 306. The first support rod 304 and the second support rod 305 are connected to the sliding rod 307 in a sleeve-type manner, so that the first support rod 304 and the second support rod 305 can move left or right along the sliding rod 307. Such an arrangement enables the first support rod 304 and the second support rod 305 to adjust the width according to the patient's body shape and shoulder width, so that patients of different body shapes can be supported by the first support rod 304 and the second support rod 305, so as to improve the practicality of the device.

According to a preferred embodiment, a limiting portion 308 is provided in the sliding groove 306. A protrusion 309 is provided on each of the first support rod 304 and the second support rod 305. When the first support rod 304 or the second support rod 305 rotates around its respective sliding rod 307, the protrusion 309 can abut against the limiting portion 308. Specifically, when the first support rod 304 rotates clockwise, the protrusion 309 can separate from the limiting portion 308, and the first support rod 304 can be slid. When the first support rod 304 rotates counterclockwise, the protrusion 309 can abut against the limiting portion 308. At this time, based on the friction force generated between the protrusion 309 and the limiting portion 308, the sliding of the first support rod 304 is limited, so that the first support rod 304 can maintain a relatively fixed shape.

According to a preferred embodiment, the vertical space of the support plate 303 can be rotatably connected to the adjustment part 2, so that the support plate 303 can rotate with the central axis of the adjustment part 2 as the rotation center. For example, a vertical space is provided on the support plate 303. A rolling bearing is nested in the vertical space. The accommodating space can be nested in the rolling bearing. By providing the rolling bearing, the support plate 303 can be rotated, thereby facilitating the adjustment of the user's orientation.

According to a preferred embodiment, a first fixing belt 310 and a second fixing belt 311 are provided on the support plate 303. The first fixing belt 310 and the second fixing belt 311 are located at both ends of the long side of the support plate 303 and below the sliding grooves 306 on both sides. The first fixing belt 310 and the second fixing belt 311 can be tied around the waist or chest of the user, so that the user can contact the support plate 303 to the greatest extent, thereby avoiding the unstable movement state caused by the irregular shaking of the patient during the movement, and finally avoiding the patient from falling during the transportation process.

According to a preferred embodiment, a plurality of rollers 101 are provided on the leg rest portion 1. The roller 101 may be a universal wheel with a brake, and the position of the leg rest portion 1 can be fixed by the brake. For example, the roller 101 may be a plastic core highly elastic transparent polyurethane side brake universal wheel. It can be installed on the leg rest portion 1 according to the screw fittings provided. That is, the present application does not improve the structure, connection structure and installation method of the roller belonging to the prior art. For the sake of brevity, the present application will not elaborate on the structure, connection structure and installation method of the roller belonging to the prior art.

According to a preferred embodiment, the base 206 of the adjustment part 2 is provided with a third support rod 203 for fixing the patient's left leg and a fourth support rod 204 for fixing the patient's right leg in a hinged manner. The third support rod 203 and the fourth support rod 204 are respectively located on both sides of the base 206. For example, the third support rod 203 can be located on the left side of the base 206. The fourth support rod 204 can be located on the right side of the base 206. The ends of the third support rod 203 and the fourth support rod 204 can be hinged to the base 206, so that the third support rod 203 and the fourth support rod 204 can both rotate downward. For example, when the third support rod 203 rotates downward, its extension direction can be switched from a state substantially perpendicular to the base 206 to a state substantially parallel to the base 206. The third support rod 203 can be used to fix the user's right leg. The fourth support rod 204 can be used to fix the user's left leg. It is understandable that fixing devices such as straps may be provided on the third support rod 203 and the fourth support rod 204 to fix the user's legs to prevent slipping.

Example 2

This embodiment is a further improvement on the above-mentioned embodiment, and the repeated contents will not be repeated here.

According to a preferred embodiment, the auxiliary support device further comprises at least one housing 401. An armrest can be provided on the leg rest 1, so that the medical staff can push the leg rest 1 to move through the housing 401.

According to a preferred embodiment, the auxiliary support device further includes a brake part 4 that can be coupled with at least one roller 101 to increase the resistance of the roller 101 during its rotation. The brake part 4 is configured to be separated from the roller 101 when the user applies a force to it, and to be in contact with the roller 101 when the user cancels the force. The position of the leg rest part 1 can be fixed by the contact between the brake part 4 and the roller 101. Specifically, the brake part 4 at least includes a friction block 402, a friction spring 403, a limit plate 404, a connecting line 405 and a handle 406. The limit plate 404 is fixedly arranged on the leg rest part 1. The friction spring 403 can be a compression spring. One end of the friction spring 403 can be connected to the limit plate 404, and the friction block 402 can be connected to the other end of the friction spring 403. The friction spring 403 can be in a compressed state at all times, and then the elastic deformation force generated by the friction spring 403 can keep the friction block 402 in contact with the roller 101, thereby achieving a braking effect. The handle 406 can be hinged on the housing 401. One end of the connecting wire 405 can be connected to the handle 406. The other end of the connecting wire 405 can be connected to the friction block 402, and then when the handle is squeezed by hand to apply force to make the handle 406 rotate around its hinge point, the connecting wire 405 can pull the friction block 402 to move upward, thereby separating the friction block 402 from the roller 101, and the leg part 1 can move.

Example 3

This embodiment is a further improvement on the above-mentioned embodiment, and the repeated contents will not be repeated here.

According to a preferred embodiment, the auxiliary support device is also provided with a control system. The control system is used to record the characteristic data of the speed and posture of the auxiliary support device, and to perform self-locking based on the analysis of the characteristic data. The control system includes a data monitoring component, a signal component and a processing component. The data monitoring component includes a speed sensor and a tilt sensor, which respectively detect the speed and posture of the auxiliary support device to ensure that the patient is always in a safe state. Each sensor is connected to the signal component. When the auxiliary support device generates data, for example, when it is detected that the device is tilted and offset, the tilt sensor will generate corresponding data and send it to the processing component and the corresponding computing terminal through the signal component. The computing terminal can be a computer for medical staff on duty, reminding the medical staff that the position and/or posture of the device has changed, and giving a warning signal to ensure the safety of the patient.

The control system provided by the present invention collects the speed and posture data of the device through a data monitoring component, and sends the collected data to a processing component and/or a computing terminal for processing through a signal component, performs self-locking and/or positioning warning processing on the auxiliary support device, thereby realizing safety protection and early warning reminders for the device.

According to a preferred embodiment, based on the different use environments of the auxiliary support device, the connection modes among the data monitoring component, the signal component and the processing component can be set to wired and wireless connections. Preferably, in a use environment with poor signal transmission efficiency, the device transmits data by wired transmission. For example, when the device is inside an elevator, due to signal isolation, the wireless transmission method cannot send the collected data to the processing component in real time, resulting in the control system being unable to operate. In response to this, the collected data is sent to the processing component by wired transmission so that the control system can operate normally. Preferably, in a wide range of long-distance use environments, the device transmits data by wireless transmission.

According to a preferred embodiment, the speed sensor may be a MEMS sensor. Through the function of monitoring acceleration and angular velocity of the MEMS sensor, the movement of the device is independently analyzed and the speed of the device is obtained. The axial direction of the acceleration and angular velocity is calibrated by the user, and the accuracy of the movement can be improved by calibration only once. Preferably, the tilt sensor may also be a MEMS sensor, which has an inclination sensor. The inclination sensor measures the angular accuracy of the device in the horizontal direction, analyzes the inclination of the device and obtains the posture of the device.

According to a preferred embodiment, the processing component includes a speed sensor, a self-locking component and a control unit. The control system composed of the data monitoring component, the signal component and the processing component is formed as a feedback system, that is, the auxiliary support device is regarded as the controlled object, the processing component is regarded as the actuator, and the speed sensor in the data monitoring component and the processing component is regarded as the detection element for collecting the feedback signal, so that the control system is formed as a feedback control system. The speed sensor detects the roller speed of the device in real time, and sends the speed data to the control unit, and the speed data of the device is also sent to the control unit through the signal component. The control unit judges whether the device has a risk of losing control based on the difference analysis between the speed of the device and the vehicle speed and the friction coefficient of the roller. When the conventional braking is performed through the brake part, the roller speed of the device is reduced at this time, and the control unit judges that there is no risk of losing control, and will not issue a control instruction to the self-locking component. This is a conventional braking state. When the control unit judges that the device has a risk of losing control based on the difference analysis between the speed of the device and the vehicle speed and the friction coefficient of the roller, the control unit sends a self-locking signal and the self-locking component acts. The self-locking component can provide a large friction force to the roller, so that the roller reduces its rotation speed under the action of the friction force, wherein the self-locking component provides friction force according to the self-locking signal sent by the control unit. The self-locking signal is a periodic sinusoidal signal. When the self-locking signal is at a high level, the self-locking component acts, and when the self-locking signal is at a low level, the self-locking component does not act, so as to realize the braking function, and prevent the roller from sending sliding friction due to excessive friction, resulting in the auxiliary support device being out of control. If the rotation speed and the vehicle speed remain at a high level after the self-locking component acts, the control unit gives a self-locking signal with a higher frequency or a longer high level or a higher duty cycle to continue to reduce the rotation speed and the vehicle speed of the device. Preferably, a speed sensor is placed on each roller, and the signal about the rotation speed of each roller is input into the control unit. The control unit monitors the motion state of each roller according to the signal sent by each roller speed sensor and determines to form a related self-locking signal. The self-locking components at each location are in a closed state when they do not receive a self-locking signal to save system power consumption. The control unit limits the speed of the roller based on the rotation speed and when the vehicle speed exceeds the first threshold, and continuously outputs a high level at the second threshold so that the self-locking component provides the maximum friction force to reduce the roller rotation speed. The reason for only providing the maximum friction force instead of locking the roller to stop is to prevent the device from tipping over and other dangerous situations after the roller is braked and locked.

Example 4

The present invention also provides a method for using the auxiliary support device, which method comprises at least the following steps:

S1: A leg-resting part 1 having a plurality of rollers 101 capable of contacting the ground is configured so that the position of the leg-resting part 1 can be changed according to the rotation of the rollers 101 .

S2: configuring the adjusting portion 2 whose first end 201 is connected to the leg-placement portion 1 so that the extending direction of the adjusting portion 2 can be substantially perpendicular to the leg-placement portion 1 .

S3: A support portion 3 is configured to be arranged on the second end 2b of the adjustment portion 2, wherein during the up and down sliding process of the support portion 3, the height between the support portion 3 and the ground can also be changed accordingly, wherein: when the patient's legs are not in contact with the ground, the patient's legs are placed in a manner that a part or all of the leg placement portion 1 is transferred to the bottom of the patient's legs based on the rotation of the roller 101, and a first support point 301 and a second support point 302 are formed between the patient and the support portion 3. When the support portion 3 moves upward so that the distance between the support portion 3 and the ground increases, the first support point 301 can apply a first support force along a first direction to the patient, so that the patient changes his posture to standing. The first direction can be a vertically upward direction. Specifically, when it is necessary to transfer the patient from the first bed to the second bed, the medical staff first lifts the patient from the first bed and makes him sit sideways on the edge of the bed, and the patient's feet are placed outside the bed. Subsequently, the auxiliary support device is moved so that a part of the leg-placed part 1 can be inserted into the space under the bed, so that the patient's left foot can be placed on the leg-placed part 1, and the patient's right foot can also be placed on the leg-placed part 1. Medical staff can adjust the first support rod 304 and the second support rod 305 to the patient's armpit by controlling the relative height of the support part 3. After the medical staff further fixes the patient's upper body on the support plate 303 through the first fixing belt 310 and the second fixing belt 311, the support part 3 is controlled to move up. At this time, based on the support of the first support rod 304 and the second support rod 305, the patient presents a standing posture. At this point, the transfer of the patient from the first bed to the auxiliary support device is completed. Similarly, when the patient needs to be transferred from the auxiliary support device to the second bed, it is only necessary to implement the above process in reverse, and the process will not be repeated here. The present application can avoid medical staff from lifting the patient off the bed by artificially holding the first support rod 304 and the second support rod 305, thereby reducing the labor intensity of medical staff. During the above-mentioned carrying process, for patients with weakness in both lower limbs and sensory impairment, medical staff will not drag the patients' lower limbs, thereby avoiding strain or abrasion of the patients.

S4: The first support point 301 is configured to be formed in a manner that the support portion 3 is in contact with the patient's armpit, and the second support point 302 is configured to be formed in a manner that the support portion 3 is in contact with the patient's chest and/or abdomen. When the length of the adjustment portion 2 is increased so that the distance between the support portion 3 and the ground increases, the second support point 302 can apply a second support force in a second direction to the patient to prevent the patient from leaning back excessively during the transition from the side-sitting posture to the standing posture, wherein the first direction is substantially perpendicular to the second direction. For example, the second direction may be a horizontal rightward direction. It is understandable that the first support point 301 and the second support point 302 are technical terms selected for the convenience of description, and do not indicate that there is point contact between the patient and the first support portion. In practice, there is surface contact between the patient and the first support portion. Since the contact surface is relatively small compared to the surface area of the human body, it is defined as the first support point 301 and the second support point 302 in this application for the convenience of description.

Preferably, in this solution, the selection of the support position for the patient is very important for supporting the patient, especially for the elderly with limited mobility. Therefore, the following steps are given: when it is detected that the patient is in a position deviating from the normal position, the positions of the force application points of multiple support points on the patient's support position are determined; according to the positions of the force application points on the determined support positions, at least one or more support parts are controlled to move and contact with one end close to the force application point, and the multiple support parts are controlled to apply the target force to the force application point of the patient's body under the support of the base, so that the patient's body returns to the normal position.

According to a preferred embodiment, when a plurality of detection units are provided on the support device, the detection object is configured as at least one patient support position and/or a state parameter of at least one patient support position corresponding to the current position of the support point, so as to select at least one action support position based on the traversed support position state parameters, so that the support part can actually act on the patient based on the selected action support position. The state parameters of the above-mentioned support position can be selected as, for example, physiological condition characteristics on the patient's body. In one embodiment, the physiological condition characteristics can include the softness of various support positions on the patient's body. In this case, the parts with higher hardness on the patient's body are preferentially selected as action support positions, which is conducive to forming a stable support for the patient; in another embodiment, the physiological condition characteristics can include various pathological positions on the patient's body. The pathological position can include the position where the patient feels pain, the position where the patient is currently or has undergone surgery, the wound position on the patient's body, etc. When selecting the action support position, the above-mentioned pathological position is preferentially excluded.

In the prior art, the support for elderly patients usually forces the elderly to return to the correct position with a fixed support structure, which forcibly forces the elderly patients to return to their correct position for any deviation from the correct posture range. However, the support for patients, especially elderly patients, should not be so "violent" in many cases. For example, there are both harder and softer parts on the body of elderly patients. The softer parts are such as the abdomen, intercostal space, etc., and the harder parts are such as bones, joints, etc. If the support part indiscriminately supports the softer parts with a preset force output, firstly, the support effect cannot obtain nearly proportional feedback, and secondly, due to the depression of the softer parts, the expected support posture detection data is offset, making the result inaccurate, and further, the soft parts of the patient are compressed, resulting in increased discomfort. In addition, the deviation of the patient from the normal posture, especially for elderly patients, often means that the patient is about to fall or fall, and this is an extremely rapid process, and a quick response to this phenomenon of the patient is required to prevent the patient from falling and getting injured. However, since the state of the patient at the moment of falling is ever-changing, if non-contact remote sensing is used to detect the support points on the patient's body that are suitable for contact support and to generate corresponding instructions to control the relevant support parts to move, this will undoubtedly be a process that consumes a lot of processor computing time, and will ultimately lead to the device not responding thoughtfully to the patient's fall, or supporting and cushioning the patient only after the patient has fallen for a considerable period of time. At this time, since the patient has accumulated kinetic energy for a considerable period of time, the "carefully selected" support parts only support individual positions of the patient, resulting in very high pressure on the supported parts of the patient, and then causing non-fall injuries to the patient.

Based on the above, this solution provides a preferred embodiment, based on the alarm information issued by the patient posture detection unit when the patient deviates from the normal posture, the processor controls at least one or more supporting parts corresponding to different positions on the patient's body to move toward the patient to contact the patient within the first time, and based on the degree of conformity between the actual detection information fed back by each supporting part and the expected posture information, withdraws the supporting parts with a conformity lower than the threshold within the second time, and controls the remaining supporting parts still supporting the patient's body to restore the patient's posture to the normal posture within the third time. The first time, the second time and the third time have a sequence.

The key point of the above scheme is that it is not to detect first and then perform support, but to support first and then detect and withdraw the corresponding support part according to the processing result. The advantage is that it can quickly respond to the emergency situation of the patient falling, and can make all the support parts contact the patient's body in the first time to prevent the patient from falling further. At this time, since the patient's accumulated kinetic energy is relatively small, the damage to the patient's body and the discomfort caused by the support part are relatively small; and this scheme makes the detection data required for the process of obtaining the alternative support points on the patient's body can be directly measured by the detector that contacts the patient's body. Compared with the use of non-contact telemetry equipment, its detection accuracy and speed are higher, and the cost of the detection equipment is lower. According to the ever-changing postures of the patient, the positions on the patient's body that are not suitable for support and the positions that are suitable for support can be directly measured without pre-existing training models, and a better or even optimal support scheme can be quickly formed, which can greatly reduce the difficulty of processor data processing calculations and reduce the patient's discomfort so that the patient can be quickly adjusted to a normal posture.
